He valued frugality and benevolent governance, and promoted civil government through the establishment of the 15 Aizu Family Precepts, the optimization of annual taxes, the corporation granary system, and pensions. In particular, the 15 Aizu Family Precepts stipulated that a ruler should not be arrogant, should put the people first, and value scholarship and loyalty, which had a major influence on the later Aizu Bushido.

Masayuki also understood the importance of learning and spread an attitude of encouraging learning and education throughout the domain. He was also interested in calendar studies, and highly valued Shibukawa Shunkai's talent, inviting him to Aizu to give lectures on calendar theory.
